Conservation of Mass
Conservation of MassIf we want to measure mass flow rate in a very simple way, we might cut open an artery and collect the blood in a beaker for a specific interval of time. After weighing the blood in the beaker to determine the mass m, we would divide it by the time t, required to collect the blood, to get the flow rate Q = m/t. However, this is not always a practical method of measuring the flow rate.Instead, consider that, for any control volume, conservation of mass guarantees that the mass entering the control volume in a specific time is equal to the sum of the mass leaving that same cont…
